Connecting to Openshift WebSocket issue - openshift

Question

I'm trying to make my OpenShift Node.js app working, but the WS connection is not working. Client error is: connection refused.
Client side factory service:
var dataStream = $websocket(localStorageService.get('wsUrl'))
dataStream.onMessage(function(message) {
var call = JSON.parse(message.data)
if (fnMap[call.fn]) {
fnMap[call.fn](call.event, call.data)
}
})
dataStream.onError(function(err) {
console.log(err)
})
dataStream.onClose(function(event){
console.log('event: ' + JSON.stringify(event))
})
var fnMap = {
"broadcastResult": function(event, data) {
$rootScope.$broadcast(event, data)
}
}
var methods = {
callFn: function(paramJSON) {
dataStream.send(JSON.stringify(paramJSON));
}
}
return methods
I'm trying to connect on the following URL: ws://myapp-myname.rhcloud.com:8000
Could you please help?
Thank you in advance,

First, you may want to make sure the websocket library, ws, is installed by declaring it in the dependencies section of your package.json and then doing another git push.
Otherwise, try the example provided in the openshift blog: https://blog.openshift.com/paas-websockets/
Specifically:
var websocket = new WebSocket("ws://myapp-myname.rhcloud.com:8000");
websocket.onopen = function(event) {
// The connection was opened
console.log(event)
};
websocket.onclose = function(event) {
// The connection was closed
console.log(event)
};
websocket.onmessage = function(event) {
// New message arrived
message = event.data
console.log(event)
};
websocket.onerror = function(event) {
// There was an error with your WebSocket
console.log(event)
};
The above at least might help point you toward a specific part of your code that's not working. Or, if the example isn't even working, it could be possibly something wrong with your cartridge, and you could try reaching out to RedHat's support.
